Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10SU
The AirTAC Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10SU is a genuine single acting, pull (spring extend) aluminum-barrel mini round cylinder with a Ø40mm bore and 10mm stroke, G1/4 air ports and a fixed rubber bumper. Air drives the pull (work) stroke and the spring returns the rod — it rests extended on air loss.

About the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10SU
The AirTAC MTBL40X10SU is a 40 mm bore, single-acting pull-type mini cylinder with a 10 mm stroke. Air retracts the M12x1.25 threaded rod, while an internal spring extends it, yielding a usable pull force of 339.1 N at 0.5 MPa. The built-in magnet (-S) enables position detection. This compact unit uses a G1/4 port and a rigid U flat-end back cover.
Its short 10 mm stroke is tailored for high-force, quick-travel tensioning tasks. The riveted rolling-packed aluminum barrel and 20 um hard-chrome plated carbon-steel rod ensure durability. A fixed rubber bumper absorbs end-of-stroke impact, as no adjustable air cushion is present. Overall length equals A + 2 x stroke, making the body longer than a push-type cylinder.
Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10SU Technical Specifications
| Model | Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10SU |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder |
| Bore size | Ø40 mm |
| Stroke | 10 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 100 mm |
Single-acting minimum working pressure is 0.2 MPa (the air must overcome the return spring). Do not apply an external load during the spring return stroke. Thread options: PT / G / NPT.
Usable Pull Force (Ø40mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 339.1 N |
| 0.7 MPa | 550.1 N |
These are the usable single-acting forces after the return spring — lower than a same-bore double-acting MBL. Size with a margin.

Where the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10SU Is Used
Pneumatic Clamping Arm
Draws a heavy clamping arm closed with 339.1 N of pull force at 0.5 MPa, using the 10 mm stroke to secure steel plates during machining.
Packaging Lid Puller
Tensioning mechanism that pulls carton flaps shut; the spring-extend fail-safe automatically opens the lid on air loss to clear jams.
Brake Caliper Return
Retracts a secondary brake caliper on 40 mm bore power; the internal spring extends the brake pad into a resting engaged state when air pressure drops.
Is the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10SU the Right Cylinder?
Select this 40 mm bore when a brief 10 mm pull stroke needs substantial force. To step down, the 32 mm bore offers 224.8 N at 0.5 MPa; stepping up is unavailable as 40 mm is the largest single-acting pull option. The MTBL40X10SU features a U flat-end back cover for rigid mounting, PT tapered port threads, and a -S magnet for CMSG, DMSG, or EMSG sensors. It requires at least 0.2 MPa to overcome the spring.
Compared to the MSBL push type, this cylinder fails safe in the extended position. Apply no external load during the spring return stroke. For replacements, verify the 40 mm bore, 10 mm stroke, G1/4 port, PT thread, U cover, and magnet. The 16 mm rod handles short-stroke loads well, minimizing rod bending risks common at longer extensions.
Quick checklist
- ✓ Usable pull force at your pressure (min 0.2 MPa)
- ✓ Fail-safe rest position (extended)
- ✓ No external load on the spring return stroke
- ✓ Magnet (S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa (min 0.2 to overcome the spring).
- check Apply no external load on the spring return stroke.
- check Avoid side load on the piston rod.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U).
- check Installation by qualified personnel per AirTAC docs.
Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10SU FAQ
This cylinder generates a usable pull force of 339.1 N at 0.5 MPa and 550.1 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring, with a maximum operating pressure of 1.0 MPa.
It is a single-acting pull cylinder, meaning air retracts the rod and the internal spring extends it. If air is lost, the spring drives the rod to a fail-safe extended home position. The -S code indicates a built-in magnet for use with AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches.
